Microsoft and Alphabet, Google's parent company, have surpassed estimated revenue in the three months to September.
Microsoft recorded revenue of $56.5b (£46.4b), a 13% rise on the same period last year and better than the $54.5b (£44.8b) predicted by analysts.
It credited the strength of its cloud computing and PC businesses for the rise.
Alphabet's revenue for the same period saw an 11% year-on-year rise at $76.7b (£63b), also surpassing estimates of $75.97b (£62.5b).
However, it's performance was still "disappointing" after its own cloud computing division reported revenue $20, (£16.4m) less than expected, at $8.4b (£6.9b).
Its quarterly growth was also down 5.5% from the previous three-month quarter, at 22.5%.
The results come as tech firms look to harness artificial intelligence (AI) to boost profits.
Microsoft will be hoping that it can boost its profits even further after the acquisition of Activision Blizzard cleared its final hurdle earlier this month.
The company's bid for the developer, best known for creating Call of Duty, previously faced resistance from regulator the Competition and Markets Authority.
